Re: finding x on a triangle.

Hi;

I am not sure what you want. Always copy the question exactly. Let's try this:

The sum of the angles of a triangle equal 180 degrees.

180 - 57 - 64 = 59

5x + 4 = 59

5x = 55

x = 11.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
